suggestions/could I be pregnant??

Rosie
alright so me and my boyfriend didn't really have sex but like he like rubbed his penis along my vagina for a while and I don't think it every really went in ( this was like 2 weeks ago) and I had like 3% of getting pregnant that day and should I be worried about being pregnant if it never really went in and maybe the possibility of precum 
anddd my boobs r kinda hurting right now and I've heard that's an early symptom of pregnancy and I really don't want to be pregnant 
so should I take a test or do y'all even think I could be pregnant
